Application led December 17, 1914. Serial No. 877,64

To all whom t may concern.'

Be it known that I, JoHN II. G1LMAN, a citizen of the United States, and a resident of Ottawa, in the county of LaSalle and State of Illinois, have invented certain new and useful Improvements in Elevators, of which the following is a full, clear, and eX- act specification.

My invention is concerned with certain improvements upon elevators of the class shown in prior Patent No. 1,089,125, ranted March 3, 1914, to myself and Albert Gilman, in which a portion of a vertical con" veyer-trough and the included conveyer chains and cups can be folded up out of the wa to allow a wagon to be driven beneathit an into dumping position.

My invention is concerned with an imrovement whereby the feed -of the rain rom the hopper to the conveyer wil be made positive, instead of depending upon the action of gravity, as has been the practice heretofore, in combinationA with a locking mechanism which serves to oppose and overcome the tendency of the suspended portion ofthe conveyer trou h to swing under the thrust of the hopper eed mechanism.

To illustrate my invention, I annex hereto three sheets of drawings, in which the same reference characters are used to designate identical parts in all the figures, of whichf Figure 1 is a sideelevationof a portion of an elevator havin my improvements applied thereto and s owing the rear end of a wagon in dumping position: Y. 1

Fi f1V is a detail onan enlarged scale,as seen in section on line B--B of` Fig. 5;.

Fig. 5 is a view of' the lowerl end of the elevator and of the hopper, as seen from the left-hand side of Fig. 1, but on an enlarged scale; v

vFig. 6 is a top plan view of the same, as seen in section on the line C-Cof Fig. 5;

Figs. 7 andS are details in section on the lines D--D and E-YE of Fig. 6.

Elevators of the class shown inprior-Patent No. 1,089,125 icontain the vertical, stationary portion 10 of the conveyer trough or framework, to whichispivoted at 11 the lower portion!v ,12 ofthe same fra-mevr url;,ff`

which is adaptedto lfewpilled by the cnam 13 from the vertical, operative position shown in full lines in Fig. 1, to the horizontal, inoperative position indicated in dotted llnes, to permit a wagon to be driven beneath Ithe elevator and intok the dumping position indicated. When the Wagon has been driven intodumping position, the lower section 12 of the framework or trough is swung down from its dotted-line to its full-line position, the hopper 14 having been previously swung out So that it will have its outer4 end extend beneath the tail end of the wagon as the elevator-section swings into place, where it is secured by the coperaton of the shoulders 15 on the locking lever 16, of which there is preferably one on each side, with the locking lugs or projections 17, which are secured to the floor of the driveway.

As the building settles, after an elevator has been installed, the beams 18 constituting the support for the second floor 19 are apt to sag, and consequently it is necessary to provide some suitable means for raising the elevator to keep it in the proper position relative to the floor of the driveway, .and for this purpose I support the upper section 10, and consequently the lower section 12, from the bars 20, which are placed on the beams 18 on either side of the section 10. On these bars 20, I place the hook members 21, which, as best seenin Figs. 1 and 2, have the horizontal top portions resting on the tops of the bars 20, and the lower horizontal,4 portions 22 connected with the top portions by: the web 23. Suitable studs 24 are supplied on either side of the section 10, preferablyby extending a rod 25 through the sectionand through the tops of'the hingestraps 26.` I place on these studs 24, eye-bolts 27, which have ltheir threaded upper ends extended through suitable apertures in the lower horii zontalportions 22 of the hook members-21,

so that by adjusting the nuts 28 on the ends of the "eye bolts 27, the elevator-frame ean'be raised as much as may be necessary to take care of the sagging of the beams 18.

The lower portion 12 of the conveyerfrarneisV preferably counter-balanced by some such mechanism, and being .thus counterbal-` anced so that it can be swung up without any d iiiiculty, it becomes necessary to lock-y said vsectionk in its operative position, for which purpose`I employ the previously mentioned locking levers 16. These levers preferably take the forni of foot levers having .treadles 29 at their .outer ends and having their inner ends pivoted to the bottom of the section 12 at 30. Each lever 16 is formed with a cam surface 31, which rides over the lug 1.7 and auton'iatically raises the lever into locking position, so that when the shoulder l5 is passed, the lever can fall or be pressed into locking position. To retain the lever 16 in locked position, I pivot thereto the ratchetbar 32, lwhich has upwardly-directed ratchet-teeth 33 'adapted to cooperate With one lof the noses of 4rthe gravity y'dog 84 'pivoted to :the framework 12, preferably in con nection with the uide piece 35 'thro h which the ratc-hetar extends. Above L1die rate-het teeth '33, I form vtheshoulder B6, rand with this construction, it will be Iobserved that `when the i'oot lever is pressed down into *locking position, it Will be held by the engagement of 'one of .the points *of the dog 34 with the ratchet. teeth 33. When it is desired `to release the frame and swing it n p into thedotted-l-ine position shown in Fig. 1, the position of the dog 34 is reversed to lthe dotted`lineposition shown in Fig. 8, and the oot lever 39 is lifted up until the othei point ofthe =dog 34 engages the shoulder 36 to hold the looking lever in the ldisengaged position shown in dotted lines 'inFig 3.

In these elevators, a series 'of cups v37 are :suspended between lthe pai-rs of sprocket ychains 38, Whi-ch chains coperate lwith sprocket 'Wheels 39 secured `on Athe shaft A40 journafled inthe `bottoni of the 'lo-Wer section 12. The :chains 538 :are driveniby 1any suitable power, vso that in operation the cups are carried u continuously to Vlitt the grain to the top o the elevator. 'The trough or vcasing 12 'has in the lower side thereof, adjacent the hopper 14, the opening '41 formed by omitting a `portion ot the'vvall, and the bottom 'of-the casing'takes the orm ora boot 42,preferablyiormed by the sheetf'meta'l cut and bent in'ltoithe shapesho-Wn. Thefend43 `of said -s'heet-metal is utilized to term the .fixedfimemberef Ea hinge 44, 'the other mein- 'berlt 'of which is boltedito the!boa/iai l46 forming thesupport Kor the -iower end of the 'hopper'l-l. This board 46 has 'lbdltedtherevtotheitwo'sidepieces '47,w-hieh are lgeneraily manguflar i'n'ftheiroutline, and form the bottornwoff the hopper except sodar 'as lthe .same isftformed by the .reeiprrocatil'izg feeding- .fciprecafting -needin -fmember -481 is revided with ratohet'bars 9,1the'teeth-foi `vv ich *face downwardly, and it is-axdnpted to reciprothe hopper is strengthened at the outer end by the cross pieces 55 and 5G extending across said end and suitably secured (o the pieces 47. The sides 57 of the hopper mai :be formed of sheet-n'letal, or in any n'lanner desired, and the) are designed to hold the material on the bottom and direct it into the boot 42.

'To reciprocate this 'feeding member 48, l. lnount loosel)7 on the outer end ot the shaft 40, which is rotated 'by the conveying mechaw nism, the sprocket `wheel 58, and I spl-ine on the outer end of this shaift y4t) the vclutch sleeve 59, 'which is moved by the -cl'utch lever 60, Aiu-icr'umed to the IWall of the section at' 61, i-nto and out of engagement with the clutch IIn'ernbeni formed on the hub of the sprocket wheel 58. A sprocketchai'n GB connects this sprocket Wheel 58 with a sprocket Wheel 64 secured on the outer end o1 the shaft 'G5 journaled in bearings 66 formed on the bracket GT secured to the under sido el t-he portion 43 of the boot. A crank arm (37 carries the crank pin G8, which is connected by the pitinan rod 69 with the pivot -bo'lt Tl) mounted in the bearing bracket 71 secured to the bar 72 bolted to the under side of the reciprocating vfeed-member 48. W' ith (he construction th-us described, it will b'e 'readily apparent that when the clutch lever t0 is -s'hifted to `'throw the reciprocatingfeed-inginechanisin inte operation, the flatter ivill ybe l`reciprocated and the teeth 49 Will torce "the grain down in'to the boot so that lit wil/ll be positively forced 'into the cups f3?, sto be carried 3up thereb7 fto the top ofthe elevator.

vrPhe l'oeleing levers '16, in addition to holding fthe vlower section 12 in its vertical position, also, as the result of the 'cea'ctiofn of the dogs 34 and the teeth 33 on the 'bars 32, serve vto support a part of the Weight-ef fthe section i12 reacting on gvthe ik'loor of the fdrivevmmthereby FWedigilngSthe levver section between 'the foor and-fthe top' section, and this action prevents any swinging-chattering, lwhich would other-wise rresult from the action thereon of the reciprocating feeding* mechanism.
